Wigglers (ハナチャン, Hanachang) are caterpillar-like insects with a segmented body and comically large nose. Wigglers are most commonly depicted as being yellow (occasionally green) and having a cheerful expression on their faces; they also wear small flowers on their heads. When enraged, which occurs when a Wiggler is injured, the creature turns a bright red color, gains solid white eyes and fangs and its flower wilts. Wigglers first appear in Super Mario World, being found in wooded areas.
Although usually generic enemies in games such as New Super Mario Bros. and Super Mario Galaxy, some appearances feature Wigglers, usually gigantic in size, as boss characters, an example being Super Mario 64. In spin-off games, the appearance of Wigglers is infrequent, although one does appear as an unlockable playable character in Mario Power Tennis and as a boss to race against in Mario Kart DS. In Mario Kart: Double Dash!! there are Wiggler Buses in the Mushroom Bridge and Mushroom City courses, which act as obstacles. Wiggler was featured again as a playable character in Mario Super Sluggers on the Nintendo Wii. He is a strong hitter with great speed, and a great asset to any Mario baseball team. Fuzzy Wigglers are found in Yoshi's Story. They are green and give Yoshi a melon.
Wigglers are the centerpiece of the mini-game "Which Wiggler?" in Super Mario 64 DS, where the aim is to locate and select the Wiggler that matches the one on the top screen by touching it with the stylus.
In Super Mario RPG: Legend of the Seven Stars, the Wigglers appear in the Forest Maze. If the player jumps on the head of the Wiggler, Mario will gain one coin. If the player manages to jump on it 10 times in a row, the player will gain a Frog Coin instead of a regular gold coin. They have 120 HP in that game.
In the Super Mario World animated series, Wigglers, though referred to as caterpillars and always drawn in their angered form, appear in various episodes. A Wiggler also makes an appearance in Super Mario Adventures comic and the taxi cabs of the Super Mario Bros. film are shown to be named Wiggler Taxi in one scene.
Mario Kart series
The likeness of Wiggler makes its first Mario Kart appearance in Mario Kart: Double Dash!!. Borrowing its green color from Super Mario Sunshine, long Wiggler-like buses appeared as part of the traffic in Mushroom Bridge and Mushroom City. Unlike the cars and trucks, which simply made racers spin out, Wiggler Buses flipped racers over. They are also immune to all items and attacks; if a player with a Starman hits a Wiggler, they will simply bounce back.
In Mario Kart DS, Wiggler is the final boss on Level 7 in Mission Mode. A racer must beat Wiggler in a race on Mushroom Bridge by collecting Starmen and staying at the fastest rate possible. Wiggler gets faster after each lap has passed.
Super Mario Sunshine
During this episode, the Wriggler is curled up on top of the sand bird tower. The goal is to point all three mirrors at it to force it off. This is done by removing the enemies off each mirror causing them to tilt in its direction. After this is done, the giant falls off and a Shine Sprite appears.
In this episode, the Wriggle is seen awake and furious at Mario's actions. It will stomp around the stage furiously. In order to defeat it, the player must spray the sand buds with water causing the sand sculptures to rise. The monster will trip and land upside down. During this time a ground pound must be done on a designated body part. Each time this is done, the Wriggler will stand up and run even faster than before. This happens until it is defeated. Three ground pounds must be done to defeat it.
When it is defeated, it will turn in to a pile of sand and sink into the ground.

Another Wiggler (or the same one...it's kinda hard to tell) later shows up when Mario and Luigi are trying to find the Attack Pieces in the woods in order to get the last of the 3 Star Cures.
Mario Party DS
In Mario Party DS, a Wiggler appeared in the first board: Wiggler's Garden and asked Mario and his shrunken friends to remove a Piranha Plant tearing up Wiggler's Garden.
